This invention relate s to mechanical movements, andparticularly thatbranch of mechanical movements pertaining to quick return motions. p

The invention has for an objecttheQprovision of a devi ce incorporating the mechanical movement which is simple in construction and positive in its operation.

In practicing the invention we provide a device applicable in one'of its embodiments to pumps, such as usedtordelivering gaso line, oil' and' similar "fluids, and this def vice is adapted to actuate the plunger for deliveringsaid fluid- VYhen utilizing such a pump it is customary to provide some} means for raisingthe plunger of the pump. This is accomplished by either turning a crank handle or by other mechanical means. It a crank handle is utilized the crank handle is turned a certain number of times in one direction to raise the pump piston, and a reverse movement of the handle'allows the pistonto descend. It is anobjectof our inventio n' to incorporate the particularmechanical movement to be described in a suitable device with the handle of the pump and the pump so that a certain number of turns of the handle in one direction will raise the pump piston, and a reverse turning of the handle will lower the piston .with a less number of turns of the handlethan was re-.

quired to raise the piston. For instance, it might require twe'lve turns ofthe handle to entirely raise the piston and three turns of the handle in a reverse direction to lower the piston. This operation is accomplished without the operator of the pumP doing more than turning the handle in one direction or the other. I V

= and the same number of turns in an opposite directio will lower the rack bar the same distance. It is the purpose of this inventiol to allow the racl: bar to be raised by a definite number of turns or the handle to its extreme limit, and a reverse turning of the handle 10 will lower the racl: bar

with a correspondingly lesser number of" opening 1 1- through which the rack bar 8 passes. The side wall 12 provi'f ith an opening 15 and a bearing plate 16 has a part received within said opening and a part adapted to engage the outer surface of the side wall 12 and to be held thereto by suitable securing means such as screws. The bearing platev is provided with a bore 1'? and the side wall 11 provided with a bore in alignment, as at 18, with anddirectly opposite the bore 17. A shaft 19 is received within the borescl? and 18 and spans the One end of said shaft 19 carries the handle member 10. Carried upon the shaft 19 and at an intermediate portion thereof, is a member 20 provided with threads 21. in the drawing said threads are shown as external quadruple square-cut threads. The member 20 is either fixed to the shaft 19 so as to turn with the shaft or it is an integral part of the shaft 19, as illustrated in Figure Loosely carriedoon the shaft 19 and within the housing a is a pinion 22 and a gear That portion of the side 11 surrouncing; the bore is enlarged so as to form a bearing for the gear 23. providedrith an enlargen'ient at so as to act asva bearing for the pinion 22. Likewise carried on the shaft 19 and between the member 20, the pinion and the 23, are collar members 25 and 2?. which collar members are each united to the shaft 19 by suitable means such as pins through the same and engaging with the shaft. The pinion 22 and the are each provided with outstanding projections or lugs 27. A nut 28 provided with internal threads is received upon the member 20, Said nut is likewise provided at each end. thereof with. outstanding lugs A friction member Z) is carried upon said nut. 28 said friction member comprises two split rings 80 and 31 with each of said split rings provided with outstanding lugs 32 and 33 and the said lugs provided with screwthma ded bores 34- and 35 adapted to receive The bearing plate 16 is also' a bolt Obviously a turning of the bolt 36 will tighten the split ring members upon the nut 28 so that it will more securely engage the periphery of the nut. The split ring 31 likewise carries an outstanding fur-rated. member 37. The side 12 carries an inwardly projecting rod 38, and both legs and of the furcated member 37' grip opposite sides of said rod 38. Obviously this construction will not permit a rotation of the member 7) when the handle member 10 is turned so as to rotate the shaft 19 and consequently cause a rotation of the member 20 which in turn will cause the nut 28 to reciprocate or move in one direction or the other relative to the member 20. If it were not for the member 7) the nut 28 would of course rotate. Obviously if the handle member were rotated clockwise the member Z2 and the nut 28 would be given a translational movement to the left looking in the plane of Figure 2 whereupon the projection 29 would engage'the projection The gear 23 would not of necessity rotate as it is loose upon the shaft 19. A reverse movement of the handle 10 would shiftthe nut and the member 5 to the right so that the projection 29 would engage'the projection 27 ofthe gear 23 and tend to retate said gear in step with the turning move- .ient of the shaft, leaving the pinion 22 free. I

To make use of the mechanism, which is described, so to actuate or reciprocate the rack bar 3, there is likewise carried within the housing; a a second shaft 4L1. Loosely carried upon said shaft is a pinion 42 provided with two hub portions, with the teeth of said pinion in mesh. with the teeth of the rack bar Fixedlvcarried upon the hub portions of the pinion 42 are two gears 43 as the pinion 42 is rotated by movement of the rack bar thegears 43 and 4-4 are likewise turned. If the gear 4:4: in mesh with the pinion 22 and the gear 43 in mesh with the gear 23. one or the other of said trainsv of will be actuated upon a turning: of the. handle 10 in clockwise or coiinter-clockwise direction. -The first train of includes the pinion 22 and the gear 4ft. andthepinion 42: the second train of ars includes the pinion 42 and the gears 1.3 and If the id is in a ratio of 3 to 1 with respect to the pinion 22 a turning of the handle 10 clockwise will slowly raise the rack bar 3 If the handle were rotated in an opposite direction the member Z2 and the nut 28 would move to the rightso that the big 27 of the gear 23 and the lug 29 would engage each other and permit rotation of the gears 23 and 43 so as to lower the rack If the gears 23 and 43 are in a 1. to 1 relation, obviously then the number of turns of the handle necessary to lower the racl; bar 3 would be materially reduced.

mean

A'device of this character will be extreme ly useful in gasoline stations,inasmuch as the gasoline tanks of motor vehicles may be quickly filled without undue effort on the part of the operator.

It will thus be seen that the invention contemplates a suitable clutch which consists of the member 6, the nut 28 and the member 20, and which clutch is adapted to actuate one or the other of two trains of gears having different gear ratios, and which gears in turn are adapted to actuate another member to cause said member to have a slow movement in one direction and a quick return movement in the other direction.

It is believed that the operation of the device will be obvious from the description above given.

It is obvious that many changes and variations and modifications may be made in departure from the particular description and showing of the accompanying drawing, in adapting the invention to varying conditions and requirements of use and service, without departing from the true spirit of the inven tion.
